Musculoskeletal Flashcards
What constitutes the musculoskeletal system?
The musculoskeletal system consists of muscles, tendons, ligaments, bones, joints, and associated tissues that work together to move the body and maintain its form.
How do the skeletal and muscular systems work together?
The skeletal and muscular systems work together to maintain body position, perform controlled motions, and support body weight. Muscles pull on joints formed by bones, allowing for movement such as sitting, standing, walking, and running.
What is the function of bones in the musculoskeletal system?
Bones form the structural framework of the body, support weight, and, in conjunction with muscles, enable movement by serving as points of attachment and leverage for muscles.
Describe the role of joints in the musculoskeletal system.
Joints, formed where two bones meet, are crucial for movement. They are surrounded by muscles and allow for various types of motion, like the knee joint enabling leg movement.
What is the periosteum, and what is its role in bone health?
The periosteum is the outer thin layer of a bone, filled with nerves and blood vessels, which nourish the bone.
What is compact bone and where is it located?
Compact bone is the smooth, firm outer layer of bone that provides strength and structure. It is the part visible when looking at a skeleton.
Describe cancellous bone and its characteristics.
Cancellous bone is located inside compact bones and has a sponge-like appearance. It is not as hard as compact bone but is still sturdy, providing internal support and flexibility to bones.
How do muscles and bones work together to enable movement in the musculoskeletal system?
Muscles contract and pull on bones at joints, causing movement. The interaction between muscles and bones is essential for activities like walking and running.
Can you provide an example of how the musculoskeletal system maintains body position?
The musculoskeletal system helps us maintain an upright posture while standing still. Explain how muscles and bones collaborate in this scenario.
What are tendons and ligaments, and what roles do they play in the musculoskeletal system?
Tendons connect muscles to bones, while ligaments connect bones to other bones. Describe the functions of tendons and ligaments in supporting and facilitating movement.
